Is there a way to vertex paint occluded vertices?
You need to have 2D Falloff option checked in Brush options and Show X ray view set(not necessary, just to see the occluded vertex) (both highlighted in the image below) It works the same for Weight painting. In all new 2.8 tutorials everybody seams to totally forgot about using this feature and I was so frustrated, when one by one everybody was just painting around objects. Finally found the answer and am happy again :)
